# Can’t Download a HAR file and the only option is MS DOS Application

When attempting to download and save a HAR file, the only option the user has is MS DOS Application.

## Applies to

- Windows
- Downloads
- File Explorer
- HAR File

## Steps

1. **Save it anyway:** Go ahead and click save, even if it says "MS-DOS Application" or looks like an app icon.
2. **Rename the file extension:** Locate the downloaded file on your computer.
  1. If you don't see ***.com*** or ***.har*** at the end of the filename, you need to turn on extensions. (In Windows File Explorer, click **View** at the top, then check the box for **File name extensions**).
  2. Right-click the file, select **Rename**, and completely delete whatever extension is there (like ***.com***).
  3. Type ***.har*** at the very end of the file name (e.g., ***8x8_log.har***) and press Enter.
3. **Confirm the change:** Windows will pop up a scary warning saying, "If you change a file name extension, the file might become unusable." Click Yes.

## Expected result

Once renamed to ***.har***, the file will instantly revert back to a standard web log file that you can successfully email to 8x8 support or upload to your ticket!

## Additional information

- What you are seeing as a "MS DOS Application" is actually a quirky Windows file-handling glitch, not a limitation of your browser.
- Windows is misinterpreting the file extension because of how it handles .com URLs or certain filenames, mistaking your export for an ancient MS-DOS .com executable application.
- You can absolutely still get your HAR file; you just have to bypass Windows trying to turn it into an app.
